srLrrrIoK-cAM HUB.

Application filed January 11, 1823. Serial No. 612,071.

To all whom it may concern:

Be it known'that we, GAnsoN E. DIXON and JAMES H. Boone, citizens of the United States, residing at Henrietta, in the county of Rutherford and State of North Carolina, have invented certain new and useful Improvements in a Split Pick-Gain Hub, of which the following is a specification.

Our invention relates to a split cam hub and has for an object to provide a device of this character, that can be placed on and removed from a shaft without disconnecting any of the other elements of the ma chine on which this invention is used.

A further object of our invention is to provide a split pick cam hub, that may be used in conjunction with the cam shaft of any type of machine now in use, that is so constructed that should the set screw break the hub may be removed from the cam shaft without the necessity of injuring the other elements of the same.

A still further object of our invention is to provide a split pick cam hub that is strong, durable, very simple and inexpensive in construction, and that, is especially well adapted to the uses for whichit is designed.

' Other objects and advantages of the invention will become apparent during the course of the following description.

In the drawings, wherein like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective view of our invention,

Figure 2 is a top plan view of the same, and 1 Figure 3 is an end view thereof.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of our invention, the numeral 5 designates a cam shaft of a loom.

Our invention is restricted to. the construction of the cam hub, that is adapted to hold the pick cam which runs the picker stick, and therefore the cam is not illus trated. The cam hub comprises a pair of semicylindrical sleeve sections 6 and 7 The sleeve sections 6 and 7 are provided near one end thereof, with the transversely or angularly extending flanges S and 9 respectively, through which are adapted to pass bolts 10 by which means the split pick curved edge 13 being cam hub'is fastened on the cam shaft 5.

Diametrically opposed arms 11 and 12 are formed integral with the sleeve sections 6 and 7 respectively, said arms being at r1ght angles to the longitudinal axis of the shaft 5. The arm 12 is substantially longer than the arm 11, and gradually tapers from its base. One edge of the arm 12 is formed with a concave surface 13, the provided so that the ad ustable screw in the cam will hold stralght to the arm. The arm 11 which is substantially shorter than the arm 12, is also a tapering armand is provided to aid in the holding of the cam to the hub. The arms 11 and 12 are provided with the trans versely extending apertures 14 and 15 respectively, by which means the cam is fastened to the arm. The arm 12 is made longer than the arm 11, so that the cam may be adusted by means of the adjustable screw carried by the cam. The cam is seated on the ends 16 and 17 of the sleeve sections 6 and 7, as will readily be understood. The sleeve sections 6 and 7 are placed on the shaft 5, and held in place by means of a set screw or a plurality thereof 18.

In use, a pair of sleeve sections similar to the sections 6 and 7 placed on the cam shaft held securely together by means of the bolts 10 which pass through the flanges 8 and 9 respectively. The set screws 18 are then tightened so as to grip the cam shaft 5, and the split pick cam hub is in place. The cam, may then be associated with the hub, being seated upon the ends 16 and 17 of the sleeve sections 6 and 7, and fastened in the desired adjusted position to the arms 11 and 12 respectively. By means of the long arm 12, having the curved edge 13, the cam may be adjusted as desired, and held in any desired position by means of the apertures 15 and 14. This split pick cam hub can be made to hold any pick respectively, are

cam on any loom that is now in use, and

therefore it may be said that this improved form of cam 'hubmay be adapted for universal use on looms.

It is to be understood that the form of our invention herewith shown and described is to be taken as the preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts disposed- 5 of a loom, and

may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claim.

Having thus described our invention, we c]ai1n:-

A split hub for the cam of a picker stick comprising a pair of like companion semioylindrical sleeve sections, radially eii'tending abutting attaching flanges formed on the sleeve sections, removable means extending through the flanges for detachably connecting the sections together, cam attachingarms formed on the sections at the eneis of said flanges, means for securing the sections on a shaft for movement therewith, and extensions formed on the sections extending beyond the flanges and arms.

In testimony whereof \Yo affix our signatures.
